Probing cosmology via the clustering of critical points

Exclusion zones in the cross-correlations between critical points (peak-void, peak-wall, filament-wall, and filament-void) of the density field define quasi-standard rulers that can be used to constrain dark matter and dark energy cosmological parameters. The average size of the exclusion zone is found to scale linearly with the typical distance between extrema. The latter changes as a function of

Living the Janus Face : The Promise and Perils of Role-Distancing for Middle Managers

Middle managers often find themselves in a challenging position: They have to impress different audiences in somewhat incompatible ways and represent and enact managerial ideals and expectations that may be detrimental to their work identities. This study explores role distancing as an alluring coping strategy. Role distancing – acts that express separateness between the individual and the enacted

Response times in rural areas for emergency medical services, fire and rescue services and voluntary first responders during out-of-hospital cardiac arrests

Aim: To increase survival in out-of-hospital cardiac arrests (OHCA), great efforts are made to improve the number of voluntary first responders (VFR). However, evidence of the potential utility of such efforts is sparse, especially in rural areas. Therefore, the aim was to describe and compare response times for emergency medical services (EMS), fire and rescue services (FRS), and VFR during OHCA

Host Plant Effects on Sexual Selection Dynamics in Phytophagous Insects

Natural selection is notoriously dynamic in nature, and so, too, is sexual selection. The interactions between phytophagous insects and their host plants have provided valuable insights into the many ways in which ecological factors can influence sexual selection. In this review, we highlight recent discoveries and provide guidance for future work in this area. Importantly, host plants can affect

Livet från den ljusa sidan : Sociologi och föreställningen om det radikalt annorlunda

Syftet med denna artikel är att undersöka föreställningar om nedväxtsamhället som ett alternativ till grön tillväxt för att förstå och hantera klimatkrisen. Med utgångspunkt i aktuell tillväxtkritisk forskningslitteratur undersöks hur författare har föreställt sig ett framtida samhälle präglat av nedväxt. Artikelns analytiska ansats är att söka urskilja mönster och tendenser genom en systematisk gThe purpose of this article is to investigate how sociological imagination can be put to work for creating notions of the radically different as an alternative to the contemporary strategy of green growth for understanding and managing the climate crisis. Based on current growth-critical research literature, it examines how a number of authors have envisioned a future society characterized by degr

Highly Hygroscopic Aerosols Facilitate Summer and Early-Autumn Cloud Formation at Extremely Low Concentrations Over the Central Arctic Ocean

Arctic clouds are sensitive to atmospheric particles since these are sometimes in such low concentrations that clouds cannot always form under supersaturated water vapor conditions. This is especially true in the late summer, when aerosol concentrations are generally very low in the high Arctic. The environment changes rapidly around freeze-up as the open waters close and snow starts accumulating

The potential of wetlands for mitigation of eutrophication and brownification

Increasing nutrient concentrations (eutrophication) and water color due to dissolved organic matter (brownification) pose continuous threats to freshwater ecosystems worldwide, threatening ecosystem services like drinking water supply. Changing the increasing trends of eutrophication and brownification on our aquatic ecosystems is challenging. However, constructed wetlands could be a potential loc

Evaluation of the effect of water on CO2 absorption in AMP and DMSO systems

Non-aqueous precipitating amine systems for carbon capture allows for CO2 desorption at lower temperatures than conventional aqueous amine systems and can potentially reduce the energy requirement for regeneration. In this work, the influence of water accumulation that may arise from humid gases entering the absorption column was investigated for absorption systems containing 2-amino-2-methyl-1-pr

Regulation of autophagy by perilysosomal calcium : a new player in β-cell lipotoxicity

Autophagy is an essential quality control mechanism for maintaining organellar functions in eukaryotic cells. Defective autophagy in pancreatic beta cells has been shown to be involved in the progression of diabetes through impaired insulin secretion under glucolipotoxic stress. The underlying mechanism reveals the pathologic role of the hyperactivation of mechanistic target of rapamycin (mTOR), w

Risk for psychiatric and substance use disorders as a function of transitions in Sweden's public educational system : a national study

BACKGROUND: To clarify, in a national sample, associations between risk for seven psychiatric and substance use disorders and five key transitions in Sweden's public educational system. METHODS: Swedish-born individuals (1972-1995, N = 1 997 910) were followed through 12-31-2018, at mean age 34.9. We predicted, from these educational transitions, risk for major depression (MD), obsessive-compulsiv

Surgical treatment of velopharyngeal dysfunction: Incidence and associated factors in the Swedish cleft palate population

IntroductionSpeech in children with cleft palate can be affected by velopharyngeal dysfunction, which persists after primary palate repair. The incidence of surgery to correct velopharyngeal dysfunction in this patient group has previously been reported as 2.6–37%. We aimed to investigate the incidence of velopharyngeal dysfunction surgery in Swedish children with cleft palate and to examine poten

Imaging in gynecological disease (27) : clinical and ultrasound characteristics of recurrent ovarian stromal cell tumors

Objective: To describe the clinical and ultrasound characteristics of recurrent granulosa cell and Sertoli–Leydig cell tumors. Methods: This was a retrospective observational study performed at Fondazione Policlinico Universitario A. Gemelli, Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS, Rome (Gemelli center). Patients with a histological diagnosis of recurrent granulosa cell tumor o

Hyaluronic Acid-Conjugated Thermoresponsive Polymer-Based Bioformulation Enhanced Wound Healing and Gut Barrier Repair of a TNBS-Induced Colitis Injury Ex Vivo Model in a Dynamic Perfusion Device

Impairment of intestinal epithelium is a typical feature of inflammatory bowel disease (IBD) that causes leakage of bacteria and antigens from the intestinal lumen and thus results in persistent immune activation. Hence, healing and regeneration of the damaged gut mucosa is a promising therapeutic approach to achieve deep remission in IBD. Currently, available systemic therapies have moderate effe

The TESS-Keck Survey. XVII. Precise Mass Measurements in a Young, High-multiplicity Transiting Planet System Using Radial Velocities and Transit Timing Variations

We present a radial velocity (RV) analysis of TOI-1136, a bright Transiting Exoplanet Survey Satellite (TESS) system with six confirmed transiting planets, and a seventh single-transiting planet candidate. All planets in the system are amenable to transmission spectroscopy, making TOI-1136 one of the best targets for intra-system comparison of exoplanet atmospheres. TOI-1136 is young (∼700 Myr), a

Mitigating footfall-induced vibrations in cross-laminated timber floor-panels by using beech or birch

Long-span floors are particularly sensitive to footfall-induced vibrations, making their analysis and design critical for ensuring occupant comfort. Cross-laminated timber (CLT) panels have high stiffness relative to their self-weight and are commonly made of spruce. Hardwoods such as birch and beech possess higher stiffness and mass density, which can potentially improve the vibrational performan

Experimental Testing and Numerical Evaluation of the Strain-softening Behavior of Birch Using a Cross-validation Calibration Approach

Softwood species are the most commonly used species in structural applications in north-ern Europe. However, in the last couple of years, utilization of hardwoods has gatheredincreased momentum, and different hardwood species, such as birch, have even been uti-lized in cross laminated timber and glued laminated timber [1]. In general hardwoodsshow an increase in strength and stiffness as compared

From master’s thesis to research publication : a mixed-methods study of medical student publishing and experiences with the publishing process

Background: Medical student master’s theses are often carried out as research projects, and some are published as research papers in journals. We investigated the percentage of master’s theses conducted by 5th -year students at the Medical Degree Program at Lund University, Sweden, that subsequently served as the basis for research publications. In addition, we explored both student and supervisor
